This is a problem I can't fix. It was a friends computer & he didn't have the patience to wait for an answer. I'm asking this for future reference. Anyway I was setting his system up as a dual boot with xp. Loaded both partitions & all seemed OK. Now it was time to xcopy his C drive. Fired up xcopy while booted in the D drive & straight away got a sharing violation of the pagefile on his C drive. This shouldn't happen. That's why you dual boot so you can use xcopy this way. Here's the weird thing. Unhide the system files on D drive & there is no pagefile file. Possibly that's why it was seeing the one on the C drive. What went wrong? Why didn't the operating system on D drive have it's own pagefile? Only thing that went a bit astray during the installation of D drive was that while I was out of the room the installation rebooted & my friend hit 'boot from CD' when it started to load again instead of leaving the thing alone. From that point we had to start the installaion again but as I said, it seemed to go OK.
